Gas Detection: No Calibration Required The GIS-320 ability to detect gases is not influenced by any calibration process and will not degrade over time. FLIR MWIR thermal core used in GIS-320 camera have been independently tested and deemed compliant with the EPA's NSPS 40 CFR part 60, subpart OOOOa sensitivity standard for optical gas imaging equipment.

  • Status of the GIS gain calibration

    GIS has the iron 55 calibration sources attached at the detector rims. They produce fluorescent lines at 5.89 keV (K-alpha) and at 6.49 keV (K-beta). The calibration source peak is being monitored by the GIS team at Univ. of Tokyo/ISAS and by the GSFC ASCA Processing team , Systematic energy shift from the correct energy and the secular energy variation indicate the current limit of the GIS gain determination.
